Drilling geological section modeling method based on topology

The invention discloses a drilling geological section modeling method based on topology. The drilling geological section modeling method comprises the following steps: S1, reading drilling data; S2, judging a drilling adjacency relation; S3, calculating a maximum common subsequence; S4, calculating topology connectivity; S5, connecting the topology nodes; and S6, carrying out drilling section topology visualization. Based on the drilling geological section modeling method based on topology, the drilling data is standardized; the method can be applied to automatic analysis and modeling of various complex geologic bodies; the three-dimensional coordinates of the topology control node are optimized based on the minimum potential energy principle; the geologic model precision is obviously improved; automatic visual processing of the drilling section topology and digital integration of geographic information are achieved, and compared with a traditional geological section map, the built drilling geological section
